For the first time since 2010, Alabama might not have the nation's top recruiting class in 247Sports' rankings. Three possible contenders:1. LSU: The Tigers have 18 recruits who are four- or five-star talents. Although they lost four-star QB Feleipe Franks (who flipped to the Gators in late November), they rebounded to swipe three-star QB Lindsey Scott from Syracuse.2. Ohio State: Former UF coach Urban Meyer continues to mine Florida; the Buckeyes have four commits from the Sunshine State, including former Tampa Catholic DL Malik Barrow.3. Ole Miss: The Rebels have a five-star quarterback (IMG Academy's Shea Patterson) and are finalists for ESPN's No. 1 safety (Deontay Anderson).Conference on the rise: Big Ten. Ohio State and Michigan could vie for the conference's first national recruiting championship of the Rivals era. Add in Michigan State and Penn State, and the Big Ten could have four top-15 classes for the first time.Conference on the decline: Big 12. No team is in the top 13 in 247Sports' composite rankings. Baylor is No. 14, but traditional powers Texas and Oklahoma are both outside the top 25. Although the Longhorns are expected to close well, they don't have a commitment from any of Texas' top 18 prospects; Houston has two of the top three.
